Conventionally, an upper frame, a bottom wall, a pair of opposing side walls whose ends are pivotally attached to the upper frame and the bottom wall and bendable in the center, and a pair of upper ends pivotally attached to the upper frame. The folding container including the second side wall is widely used in the field of distribution because it can be stacked when the article is stored, and the volume can be reduced when the article is not stored.
[0003]
There is already known a container in which an opening is provided in a side plate, and a side lid for opening and closing the opening is provided in this opening. For example, Japanese Patent Publication No. 1-56982 discloses a side portion on a side portion of a container. An opening is provided, and a side lid that opens and closes the side opening is rotatably attached. A lower bearing is provided below the left and right edges of the side opening of the container, and a link is provided on the lower bearing. The upper end of the side cover is attached by a shaft, and the lid side bearing portion at the lower part of the side cover is attached to the horizontal through hole provided at the lower end portion of the link portion by the shaft. A mounting structure for a side lid of a container is described in which a through-hole is provided at a position corresponding to a horizontal through-hole provided in a lower portion of a link portion, and this through-hole serves as a second lower bearing portion.
[0004]
[Problems to be solved by the invention]
The side cover mounting structure of the above prior art has the advantage that the opening of the side cover can be selected at 180 degrees or 90 degrees by changing the shaft that passes through each through hole. Or since it protrudes 90 degree | times sideways, it still has the problem that extraction of the stored thing from an opening part is not necessarily easy. That is, when the side lid is opened 180 degrees downward, the opening of the container underneath is stacked in a stacked state, so that it is difficult to take out the contents from the lower box, and the side lid is turned 90 degrees sideways. In the opened state, the side lid may be in the way, and the worker can take out the contents only when the arm is considerably extended, or it may be difficult to remove the contents in the back. .
[0005]
In addition, in a conventional opening / closing mechanism using a side lid, a special locking mechanism manufactured separately must be provided between the side lid upper part and the side wall opening upper part. There is still room for improvement in that it costs money for

  The present invention relates to a container in which an opening is provided in a side plate and a side lid for opening and closing the opening is provided in the opening so as to be rotatable. (A) An upper member and a lower member that can refract the side lid via a hinge. (B) the side lid lower member is pivotally connected to the side plate below the opening via the link, and (c) the link and the lower side plate are rotated by the first shaft. The link and the lower side cover member are connected so as to be movable, and the second shaft passing through the long hole of the lower side cover member is connected so as to be rotatable and pullable.(D)An engaging portion is provided between the upper and lower members of the side lid and the side plates on both sides of the opening to lock the movement in the horizontal direction and to be disengaged in the pulled out state.as well as (e) Having a recess for receiving the upper end portion of the side lid in which the side plate below the opening is folded;Is a feature.
[0009]
In the present invention, with the configuration (a), the side lid can be folded, the opening operation can be performed with the side lid folded, and the opening can be closed with the side lid extended straight.
[0010]
Further, with the configuration (b), the entire side lid can be rotated with respect to the side plate, and the side lid can be easily opened and closed. In combination with the method (c), the side lid is rotated and locked and unlocked smoothly.
[0011]
Further, in the configuration (c), the link is provided so as to be rotatable with respect to the lower side plate by the first axis, and accordingly, the link is rotatable about the first axis. The lower side cover member is provided so as to be rotatable with respect to the link by the second shaft, and accordingly, the lower side cover member is rotatable about the second axis. Moreover, the side plate lower member is provided with a long hole (a long hole extending in the vertical direction in the locked state), and the second shaft is provided so as to pass through the long hole. The whole can be pulled out in the direction of the long hole.
[0012]
Furthermore, as in the configuration (d), the horizontal movement is locked between the upper and lower members of the side lid and the side plates on both sides of the opening, and the engagement is released in the pulled out state. In the state where the side lid is pulled upward, the side lid and the side plate can be disengaged and the side lid can be folded and rotated, while one side lid is pulled down. Then, the side lid and the side plate are engaged with each other through the engaging portion, and the opening can be closed. In addition, when the opening is closed with the side lid, the upper member and the lower member of the side lid are both engaged with the side plates on both sides of the opening via the engaging portion. The advantage of less is achieved.
[0013]
In the present invention, the hinge of the side cover may be a valley foldable hinge or a mountain foldable hinge when viewed from the outside of the container. In order to prevent the lid upper member from hanging freely, it is advantageous that the hinge is a valley foldable hinge. That is, by making the side lid upper member and the lower member valley-folded, the free movement of the upper member is restricted by the lower member and the side plate, and the upper member does not hang down. In addition, in the folding container, the long side plate is provided so that it can be valley-folded via a hinge. Thus, the entire side plate can be folded while the side lid is engaged with the side plate.
[0014]
In the present invention, the long hole provided in the side lid lower member should have an upward pulling dimension sufficient to release the engagement state at the engagement portion between the side lid and the side plate.
[0015]
In the container of the present invention, since the upper member and the lower member are provided so as to be foldable via the hinge, only the upper member of the side lid is opened depending on the type of the article and the storage state of the article. You can also fold and open the entire side lid.
[0016]
To perform the former opening, the side cover is pulled upward, the engagement state between the upper member and the corresponding side plate is released, while the engagement state between the lower member and the corresponding side plate is maintained, It pivots forward with the hinge as the center, and an opening by only the upper member becomes possible.
[0017]
Also in the case of performing the latter opening, the folded side lid can be made to hang downward, or can be made to extend substantially horizontally. In any of these cases, the side lid is folded, so there is no hindrance to the removal or storage operation of the contents from the opening. There is an advantage that it is easily performed.
[0018]
In the case of a pendant opening, the link preferably has a pull-out dimension sufficient to hang the folded side lid. That is, in this hanging state, the link is in a state of being rotated almost horizontally and forward, but in this state, the upper member of the side lid is accommodated between the lower member of the side lid and the side plate. There must be space left.
[0019]
Further, in the case of a horizontal opening, by providing a recess for receiving the upper end portion of the folded side lid upper member on the side plate below the opening, the folded side plate can be maintained substantially horizontal. it can. In this aspect, in the stacked container, it is easy to open and close the opening by opening the opening from the container below the container in which the opening is already open.
[0020]
The engaging portion used in the present invention is composed of a downward receiving provided on the side plates on both sides of the opening and a locking piece provided on the side lid, and the structure of the engaging portion is the simplest and least complicated. However, it is desirable to make the engagement state of both reliable and strong. In other words, the locking piece of the side lid is inserted into the receiver from above, so that the locking state is ensured, and the locking can be released by removing it from the receiving piece.
[0021]
In the container of the present invention, it is preferable that the side plate above the opening is provided with a bendable side lid gripping finger insertion portion defined through a through-cut-out portion. It is easy to grip the top edge of the lid and pull out the side lid upward, and with the side lid closed, it is possible to reduce the useless opening area of the side plate as much as possible. It is possible to effectively prevent the entry of dust etc.
[0022]
The present invention includes an upper frame, a bottom wall, a pair of opposite side walls that are pivotally attached to the upper frame and the bottom wall and bendable in the center, and an upper end pivotally attached to the upper frame. The present invention can be applied particularly advantageously to a folding container including a pair of second side walls. As already pointed out, the side lid can be folded, and the side lid upper member and the lower member are engaged with the corresponding side plates, so that the entire side plate is folded while the side lid is engaged with the side plates. Therefore, no special troublesome operation is required for folding.
[0023]
The opening / closing operation of the opening in the container of the present invention is performed as follows.
(1) When the opening is closed by the side cover, the second shaft is located below the long hole, but the side cover can be lifted upward by the length of the long hole. First, the side lid is pulled upward. Thereby, the engagement between the upper and lower members of the side lid and the side plates on both sides of the opening is released.
(2) By releasing the engagement, the upper member and the lower member of the side lid can be folded via the hinge therebetween, and the side lid can be rotated around the first axis. With the side lid folded, it is rotated toward the operator.
(3) Fix the opened side lid in a state in which the folded side lid is suspended downward from the link, or the upper edge of the upper member of the side plate is formed in the concave portion of the side plate so that it extends almost horizontally. Is done. In this state, the article is put in and out through the opening of the side plate.
(4) When the loading / unloading of the article is finished, the folded side plate is rotated in the opposite direction to the above, and the side cover upper member and the lower member are straightened and the side cover is pulled out. The upper member and the lower member and the side plates on both sides of the opening are locked by the engaging portion, and the opening is closed by the side lid.
[0024]
According to the present invention described above, the opening operation in a part of the side lid and the opening operation in the folded state of the entire side lid are possible, thereby depending on the type of the article and the filling state, The open state can be selected, and the removal operation and storage operation from the opening can be easily performed even in a stacked state, and the locking operation to the side wall of the side lid is also performed as a separate lock. There is an advantage that it is performed easily and reliably without using a mechanism, and the opening is reinforced by the engagement between the side lid and the side plate, and as a result, the strength reduction of the opening is suppressed to a low level.
